Jesper Schulz-Wedde 62dabf9a11 Co-locate AL samples next to their knowledge articles
The /samples/ top-level tree is replaced with sibling files in each
knowledge-layer folder. An article and its demonstrations now live
side-by-side:

  microsoft/knowledge/<domain>/<slug>.md
  microsoft/knowledge/<domain>/<slug>.good.al
  microsoft/knowledge/<domain>/<slug>.bad.al

Rationale:
- Proximity. An article and its paired samples are one unit; the
  filesystem now reflects that.
- Layer ownership. Samples inherit layer precedence for free -- a
  /custom/ fork can override an article and its samples atomically,
  which the shared /samples/ tree previously made awkward.
- Trivial migration path. Action-skill source globs
  (*/knowledge/<domain>/**/*.md) are unchanged; sample discovery is a
  sibling-filename lookup.

Changes:
- git mv of all 65 sample files from samples/<domain>/<slug>/{bad,good}.al
  to microsoft/knowledge/<domain>/<slug>.{bad,good}.al (history preserved).
- Update See-sample references in all 37 articles that ship samples.
- skills/read.md: replace the no-code-blocks bullet with a pointer to a
  new Sample files section that fully specifies the sibling convention,
  the kinds (good/bad + forward-compatible), multi-technology rules,
  demonstration-only status, and layer-precedence behaviour.
- skills/write.md: update the samples pointer to match.
- README.md: annotate the knowledge tree with the sample sibling shape.
- samples/README.md deleted; content lifted into skills/read.md.
- Both generators (C:\temp\gen_performance_knowledge.py,
  C:\temp\gen_security_knowledge.py) updated to emit at the new paths
  and to stop writing samples/README.md. Re-running them is idempotent
  against the committed layout.

# Use NonDebuggable when parsing secrets
> **Seed article.** Converted from an existing security-review prompt to bootstrap the BCQuality security corpus. Domain stewards should expand, restructure, and refine as needed.
## Description
SecretText transit (assignment between SecretText variables, parameters, and return values) is protected automatically. Extracting a secret from a Text source — for example, reading an access token out of a parsed JSON response — is a legitimate Text-to-SecretText conversion during which the plaintext exists. The [NonDebuggable] attribute prevents debuggers (regular and snapshot) from inspecting the procedure's locals, parameters, and return at that moment.
## Best Practice
Apply [NonDebuggable] to any procedure that reads a response body, parses it, and assigns the extracted secret to a SecretText out-parameter or return. Keep the procedure narrow: it SHOULD do the minimum work required to obtain the SecretText, and nothing else.
See sample: `use-nondebuggable-when-parsing-secrets.good.al`.
## Anti Pattern
Parsing a token response in a normal (debuggable) procedure. The plaintext token is visible in debug sessions and snapshots taken during the parse.
See sample: `use-nondebuggable-when-parsing-secrets.bad.al`.
